SPECIFICATION forming part of Letters Patent Ne 706,504, dated August 5, 1902.

Original applioationled November 8, 1898, Serial No. 695,875 Eeneweddanuary 22. 1901. Serial No. 44,301. Divided and this application filed July 24,1901. SeriaiNo. 69,605. (No model.)

T0 all whom, t may concern.-

Be it known that I, GEORGE WASHINGTON',` of New Brighton, in the county of Richmond` and State of New York, have invented certain new and useful Improvements in Hydrocar;` bon Incandescent Lamps; and Ido herebydeclare the following to be a full, clear, and exact. description of the invention, such as will en:

able others skilled in the art to which itapperf, y

o ward passage between the mixing and intertains to make and use the same. u My invention relates to an improvenn e`.ntfi` n. hydrocarbon incandescent lam-ps, arrdfis "a` division of my application No. 695,875, filed,Y November 8, 1898, renewed January 22,1901.; and it consists in the parts and combiriatioigsl of parts, as will be more fully described'mu dv pointed out in the claims. H

In theaccompanying drawings, Figure lisV a view in longitudinalsection of my lamp. Fig. 2 is a top plan View of the base of same, and Fig. 3 is a View on Vthe line y fy of Fig.f.1. 1 represents a vaporizing-tube providedatg its lower end with a removable plug 2, having a central longitudinal opening forthe passage of the needle-valve and .isfoonnected to the oil-cup 3. The upper end of; the vaporizng, tube carries or is directly belowtherjet-nozzle. 4., which latter has alltapering bore throughl which the needle-valve passes. Theupper end of the vaporizing-tube is secured to thel base 11, which latter actsas a heat-accumuf. lating body for heating theivaporizing-tube'.

Secured to the base l1, which,together with the tube 13, forms an outer casing with the burner tube or cap at the upper end, is the upwardly-projecting mixingtube 12, into which the vapor is discharged, and surround-` ing the mixing-tube 12 is the intermediate' tube 27, closed at a point above themixingtube. Theintermediatetube27issurrounded by the burner-tube 13, having the perforated burner-cap 14.

Passing through the sides of the 'burner and intermediate tube 27 and discharging into the mixing-tube 12 are the airfinlet pipes 17.

The vapor as it issues from the vapor-escape nozzle 4. draws in air through the air-inlet pipes 17, and the air and vapor thus brought together are commingled and pass upwardly within the mixing-tube and pass into the in- Itermediate tube or casing 27, and as the latclosed at its upper end bya diaphragm land is `supported with its lower end above the base jljlthe mixed air and vapor pass downlwardly-between the casing or tube 27 and itheinixing-tube 12 and then under the lower VIedge .of `the former into the outer or burner jtube lliqand is burned under a mantle.

Pant of the mixed air and vapor in its down- .3mediatetubesescapesthrough the j et-oriices 22 inthe base-lljof the casing and is burned in d irectcoiitact with the base 1l, the flames from vtheA several jets or auxiliary heater irnpingingagainst the flanges 23 and 24, and thus 'quickly heating the base and maintainling4 it and the vaporizing-tube connected ltherewith at such a temperature'as to quickly `'vaporize the oil within the Vaporizing-tube. Inthis device the jet-orifices 22 forthe vaporfgenerating iiame are in a plane above the ,lowergendbf the intermediate `tube or casing. `,[Itlenceit will be seen that a portion of the mixed air and Vapor` always escapes through `said jet-orifices.i1-respective of. the pressure Vwithin the commingling-tube. In order,how `to'limit orregulate the passage of the ai. r 11d-vapor to` the burner,l have. provided thering-valve 28. This valve rests on the .base llor within thelower end of the burnertube' and is provided witha depending stem 29,; which passes through the sleeve 310, carried by the base. By -liftingythestem it will be seen that the passage between the tube or casing 27and the burner-tube 13 can be cut oit' more or less, thus permitting me to confine, if` necessary or desired, approximately z all the vapor within the casing 27, sufficient, however, escaping around the intermediate tube or casing to maintain a small or pilot flame at the burner.

The vaporization of the oil may be started by heating the generating-tube 1 in any-manner; but I prefer to provide the latter with a starting-cup designed to contain sufficient alcohol or oil for the initial heating of the generating or vaporizing tube. After the vapor begins to form, part of it, as before eX- plained, passes downto the vapor-escape oriices 22 in the base 11 and is ignited by a torch IOO or by the-flame from the starting-cup and in a few seconds heats the base 1l to a temperaturesufcient to vaporize the oil therein.

v wholly extinguished by cutting off completely the supply of vapor to the mixing-tube, I prefer to have the vapor-valve 5 so constructed and arranged that the closure thereof will not completely check the flow of vapor, but will permit sufficient to pass to maintain the vapor-generatin g flames against the base 1l and a pilot or small flame at the top', the iames being wholly extinguished by cutting off the supply ot' oil to the vaporizing-tube.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patentfis- 1. A vapor-burner comprising an outer casing having a burner-tube arranged at its upper'end, a mixing-tube within said casing, an intermediate tube'within the casingand surrounding said mixing-tube, and a diaphragm in said intermediate tube above the open upper end of the mixing-tube, a Vaporizer penetrating the bottom of the casing and arranged to discharge Vapor into the mixingtube, air-inlet tubes penetrating the sides of the casing and arranged to discharge air intoA said mixing-tube, and a vapor-j et burner connected to the base of said casing and arranged to heat said vaporizer, substantially as described.l

2. A-vapor-burner comprising an outer casing carryinga burner, a mixing or commingling tube Within said casing, an intermediate tube closed at its top and open at its bottom and vsurrounding said Vaporizing-tube, a vaporizer arranged to discharge vapor into the mixing-tube, air-inlet tubes discharging into said mixing-tube, and a vapor-j et burner connected to the base .of said casing and arranged to heat said vaporizer, substantially as described.

3. A vapor-burner comprising an outer tube or casing carrying a burner, a mixing or commingling tube Within said casing, an intermediate tube closed at its top and open at its bottom, a Vaporizer arranged to discharge vapor into the mixing or commingling tube, air-pipes leading to the mixing or commingling tube, a Valve for controlling the ow of mixed air and vapor from the intermediate tube t'o the outer tube or casing and yan auxiliary 'burner adjacent to the vaporizng-tube for heating the latter.

4. In a lamp of the class described, the combination with a vaporizer, of a burner provided with tubes disposed one within another to form three communicating passages connected to cause the Vapor to pass through the intermediate passage in the opposite direction from that in which it passes through the other two passages, and an airsupply tube extended across two of the said passages and communicating with the innermost tube above the Vapor-outlet of said Vaporizer to supply the vapor issuing from the vaporizer with air, substantially as and for the purpose speciied.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

GEORGE VASHINGTON.
